Natural Vegetation
Refers to a plant community that has grown naturally without human intervention and has adapted to its environment over a long period.
Tropical Evergreen Forests
Dense forests found in regions receiving more than 200 cm of annual rainfall, where trees do not shed their leaves all at once.
Tropical Deciduous Forests
Also known as monsoon forests, these are the most widespread forests in India, found in areas with 70 cm to 200 cm of rainfall, where trees shed their leaves during the dry season.
Mangrove Forests
Salt-tolerant forest ecosystems found in coastal regions, estuaries, and deltas, particularly prominent in the Sunderbans delta.
Social Forestry
The management and protection of forests and afforestation on barren lands to help environmental, rural, and social development.

Frequently Asked Questions
What is the main difference between evergreen and deciduous forests?
Evergreen forests remain green throughout the year as they do not shed all their leaves simultaneously due to high rainfall. Deciduous forests shed their leaves during the dry season to conserve water.
Why are mangrove forests important for the coastline?
Mangrove forests act as a natural barrier against cyclones, tidal surges, and coastal erosion, while also providing breeding grounds for marine life.
What measures are taken for forest conservation in India?
Measures include implementing the National Forest Policy, promoting social forestry, establishing wildlife sanctuaries and national parks, and encouraging community participation like Joint Forest Management.
